VENTILATOR.

Specification of Letters Patent.

Patented Nov. 27, 1917..

Application filed February 5, 1916. Serial N 0. 76,239.

To all whom it may concern.

Be it known that I, HARVEY F. MARaN- VILLE, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Ventilators, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings.

This invention relates to roof connections for ventilators, and has for its object to provide an adjustable roof plate or connection by means of which a ventilator can be attached or applied to roofs of various forms, such as flat, peaked, or slanting. Ordinarily after a person buys a Ventilator he has to engage a local tin-smith to construct a base, which always has to be specially made, and adds considerable to the cost. The present invention provides an adjustable base for the ventilator, which can be applied to roofs of various types, without the construction of special fittings.

In the accompanying drawings, Figure 1 is a perspective view of a ventilator mounted upon the ridge of a peaked roof. Fig. 2 1s a vertical cross section of the devlce on the line 2-2 of Fig. 3. Fig. 8 is a vertical section on the line 3-3 of Fig. 2. Fig. 4 1s a perspective view of a part ofthe ventilator body. Figs. 5 and 6 are perspective vlews .of the adjustable parts which rest on the roof. Fig. 7 is a detail in section of a joint. Fig. 8 is a side elevation show ng the devlce applied to a slanting roof.

Referring specifically to the drawmgs, 6 indicates a roof and 7 the neck of a ventilator or cowl of suitable construction. This neck is rectangular in horizontal section, and rests upon a body shown in Fig. 4, having two parallel flat sides 8 and two segmental ends 9. The lower edge of one end of the sides of the body is beveled or cut oil at an angle, as indicated at 10, to afiord room for any ordinary adjustment. The segmental ends 9 are coaxial with pivots 11 comprising bolts by means of which the base members are attached to the body. The two base members are shown in Figs. 5 and 6. @ne of them consists of two side walls 12 and a segmental connecting wall 13 at the outer end thereof, with a flange 14 extending around the lower edges of the sides and the segmental wall, said flange being adapted to rest on the roofing boards and to be lapped The inner lower corners of the Walls 12 have holes 15 to receive the pivot bolts 11, and the member is slotted at the joint, as indicated at 16, to receive the side walls of the other base member.

This other base member has two side walls 17, a segmental wall 18, a bottom flange 19, and holes 20 in the side walls for the pivot bolts. The walls 13 and 18 describe an arc concentric to the pivotal axis.

lVhen the parts are assembled, the two base sections are joined with the inner ends of the sides 12 fitting between or lapped with the sides 17, the inner ends of the latter projecting into the slots 16. The body is then set on the base, and the parts are connected by the pivot bolts 11. The segmental walls 13 and 18 fit closely within and against the segmental ends 9 of the body. A lead flashing sheet 21 is interposed between the walls 8 and the flanges of the base members to cover and prevent leak through the slots 16, and the walls of the base members are of sufficient height to lap the body under all ordinary conditions.

By the means described, the base members maybe adjusted on the pivots to various posltions according to the roof. As shown in Fig. 1, said base members are applied to the ridge of a roof, extending at an angle on opposite sides thereof. Tn Fig. 8 the base members are in alinement on a slanting roof. One member of the base is or may be fastened to the body by one or more bolts 22, to support the ventilator in position, and additional bolts may if desired, be inserted through the other member, after the neces sary adjustment is effected.

The device provides a convenient means for attaching a ventilator to roofs of various kinds without special fittings.

Having thus described my lnvention, what claim is 1. In a ventilator adapted to be fitted to either the ridge or the slope of a roof, the combination of a main body portion the lower end of which has parallel side walls and segmental end walls, one end wall being shorter than the other, the lower edges of the side walls being beveled and extending at an angle to each other from the middle, with a base comprising two members having side Walls pivoted to the side walls of the body at the middle of the latter, and segmental end walls fitting within the end walls of the body, said base members being tilt still adjustable on the pivots with respect to each other and to the body.

2. In a ventilator adapted to be fitted 'to either the ridge or the slope of a roof, the

,7 cylindrical surface, said members having segmental end walls fitting within the end walls of the body and bottom flanges adapted to rest on the roof.

3. In a ventilator, a base having apair of upright parallel fiat sides and a pair' of transverse ends, said ends defining segments of a cylindrical surface whose axis intersects said sides perpendicularly at a point adjacent their lower edges, one of said ends bemenses ing higher than the other, and the lower edges of said sides and ends being formed with a laterally extending securing flange.

4. In a ventilator, a base having a pair of upright parallel fiat sides and a pair of transverse ends, said ends defining segments of a cylindrical surface whose axis intersects said sides perpendicularly at a point adjacent their lower edges, one of said ends being higher than the other and the lower edges of said sides and ends being formed with a laterally extending securing flange, and a body member having fiat parallel sides adapted tooverlap and engage the side walls of said base, and having arcuate ends adapted to overlie and engage the ends of said base and having a radial hollow neck adapted to communicate with the interior of said base, one of the end walls of said body being shorter than the other and said side walls being beveled to meet said shorter wall,

In testimony whereof, I hereunto affix my signature.

HARVEY MARANVILLE.
